DEVICE FOR DERAILING CARS.

SPECIFICATION forming part of Letters Patent No. 383,723, dated May 29,1888.

Application filed February 16, 1888. Serial No. 261,266. (No model.)

which will enable a truck to be readily I'B', moved from a permanenttrack, and at right angles thereto.

In the drawings, Figure 1 is a transverse section of a truck providedwith my improvements. Fig. 2 is a like view showing the auxiliarydevices brought into position for operation. Fig. 3 is a detail enlargedsection to show more clearly the fitting of the wedges.

As shown in the accompanying drawings, a

' hand-truck has hangers A depending from the sides B of its platform 0.The usual axles, a, bear in the hangers A and carry the wheels b. Withinthe dimensions of the sides B and axles a is a rectangular frame, D,which is provided with dependinghangers c, which are arranged at rightangles to the hangers A. Smaller shafts, d, bear at their ends in thehangers c, and are provided with wheels, 6, of smaller tread and gagethan the wheels b. A strong elliptical spring, E, is centrally securedat its center upon the under side of the platform 0 by bolts f. It isproposed to employ one of such springs at each end, and each has itsfree ends sprung under lugs g, located on the sides of the hangers 0.

Longitudinal bars h are secured upon the upper side of the auxiliaryframe beneath the platform and are each provided with vertical bolts I,which play through metal thimbles k on the platform, and serve to guidethe anxiliary frame relative to the platform. Each of the said bars h isprovided with a slot or recess, through which is adapted to i move awedge-shaped block, Z, the lower inclined face of which bears in theslot of the recess, while the. horizontal face on the top of the blockbears against the under side of the platform.

A transverse shaft, F, is provided with oppositely extending screwthreads, each of which engages a threaded opening in each of the blocksZ Z, which are reversed relative to each other. One end of the shaft Fextends beyond one side of the truck, where it is provided with anoperating-crank, G.

When the truck is being used on the permanent track, the auxiliarydevices occupy the position shown in Fig. 1, where they are representedas being held up out of position by the power exerted by the springs E.When it is desired to remove the truck from the permanent track,temporary rails m m are laid transversely across the main-track rails,asindicated in Fig. 2,the said rails m occupying the same vertical planeas the tread of the wheels 6 c. The shaft F is then operated to move theblocks Z awayfrom each other, their wedge bodies forcing the auxiliaryframe downward to place the wheels 6 upon the rails m and lift the maintruck from the permanent rails. The entire device can then be rolledtransversely from the main track.

A convenient arrangement of temporary track is that shown in Fig.2,wherein parallel rails N N are located at right angles to thepermanent track, and each of the rails N is provided at its inner endwith a tongue, 0, and a supporting-foot, P. The rails m m are pivotallyconnected to the tongues 0, so that when placed across the rails N theywill bein line with the same. When the truck is shipped upon the railsN, the rails m m can be turned to the vertically-inclined positionrepresented by dotted lines, Fig. 2, so as to be out of the way.

The improvements explained are of simple and durable character andreadily operated to secure the desired object. It will be readilyunderstood that the flexile power of the springs assists in raising andsustaining the auxiliary parts. i

1. The combination, with the truck, of an auxiliary frame mounted belowthe same and provided with wheels at right angles to the wheels of thetruck, and means for raising and lowering said auxiliary frame, as setforth.

2. The combination, with a truck, of an auxiliary frame provided withwheels, means for raising and lowering said auxiliary frame, andsupplemental rail-sections, substantially as set forth.

6. The combination, with the truck and the auxiliary frame, of boltsconnected to the latter and playing through openings in thetruckplatform, and means for raising and lowering 20 said auxiliaryframe, substantially as set forth.

7. The combination, with the permanent track, of the rails N, providedwith tongues and feet at their inner ends, and rails m, pivoted to saidtongues, substantially as set forth, 2 5 In testimony that I claim theforegoing as my own I have hereto affixed my signature in I presence oftwo witnesses.
